/**
 * This class provides encoding and decoding methods for writing and reading
 * ZigZag-encoded LEB128-64b9B-variant (Little Endian Base 128) values to/from a
 * {@link ByteBuffer}. LEB128's variable length encoding provides for using a
 * smaller nuber of bytes for smaller values, and the use of ZigZag encoding
 * allows small (closer to zero) negative values to use fewer bytes. Details
 * on both LEB128 and ZigZag can be readily found elsewhere.
 *
 * The LEB128-64b9B-variant encoding used here diverges from the "original"
 * LEB128 as it extends to 64 bit values: In the original LEB128, a 64 bit
 * value can take up to 10 bytes in the stream, where this variant's encoding
 * of a 64 bit values will max out at 9 bytes.
 *
 * As such, this encoder/decoder should NOT be used for encoding or decoding
 * "standard" LEB128 formats (e.g. Google Protocol Buffers).
